STM8库函数的中断问题

如图,我一般是在main.c中位域出时间标志位，struct                            //位域出时间平台标志位 {
  unsigned char flag_1mS :1;
  unsigned char flag_2mS :1;
  unsigned char flag_4mS :1;
  unsigned char flag_50mS :1;
  unsigned char flag_100mS  :1;
  unsigned char flag_500mS  :1;
  unsigned char flag_1S    :1;
  unsigned char flag_2S    :1;

}Time = {0,0,0,0,0,0,0,0};

然后把中断函数写在main.c中，在里面构造时间平台
INTERRUPT_HANDLER(TIM1_UPD_OVF_TRG_BRK_IRQHandler, 11)
{
  TIM1_ClearITPendingBit(TIM1_IT_UPDATE);  //清除TIM1溢出标志

  static unsigned char Cnt_1mS = 0;
  static unsigned char Cnt_2mS = 0;
  static unsigned char Cnt_100mS = 0;
  static unsigned char Cnt_500mS = 0;
  static unsigned char Cnt_1S = 0;

  Cnt_1mS++;
  if(Cnt_1mS == 10)
  {
Cnt_1mS = 0;
Time.flag_1mS = 1;

Cnt_2mS++;
if(Cnt_2mS == 2)
{
   Cnt_2mS = 0;
   Time.flag_2mS = 1;

   Cnt_100mS++;
   if(Cnt_100mS == 50)
   {
      Cnt_100mS = 0;
      Time.flag_100mS = 1;

      Cnt_500mS++;
      if(Cnt_500mS == 5)
      {
      Cnt_500mS = 0;
      Time.flag_500mS = 1;

      Cnt_1S++;
      if(Cnt_1S == 2)
      {
         Cnt_1S = 0;
         Time.flag_1S = 1;

      }
      }
   }
}
  }
}

再在主循环里面判断标志位来确定时间，执行任务
for(;;)
  {
if(Time.flag_500mS == 1)
{
   Time.flag_500mS = 0;
   LED_Running();
}

  }

以前一直是用寄存器的，没有问题，现在改库函数了，报错重复编译。可是stm8s_it.h里面不是声明了中断函数了吗，main.c中我也引用了stm8s_it.h，为什么会这样呢？
